A fire-mist and a planet,
A crystal and a cell,
A jellyfish and a saurian,
And caves where the cavemen dwell;
Then a sense of law and beauty,
And a face turned from the clod--
Some call it Evolution,
And others call it God.

Most species do their own evolving, making it up as they go along, which is the way Nature intended. And this is all very natural and organic and in tune with mysterious cycles of the cosmos, which believes that there’s nothing like millions of years of really frustrating trial and error to give a species moral fiber and, in some cases, backbone.

The rise of every man he loved to trace,
Up to the very pod O!
And, in baboons, our parent race
Was found by old Monboddo.
Their A, B, C, he made them speak,
And learn their qui, quae, quod, O!
Till Hebrew, Latin, Welsh, and Greek
They knew as well's Monboddo!

Observe constantly that all things take place by change, and
accustom thyself to consider that the nature of the Universe
loves nothing so much as to change the things which are, and to
make new things like them.

Said the little Eohippus,
"I am going to be a horse,
And on my middle fingernails
To run my earthly course!
. . . .
I'm going to have a flowing tail!
I'm going to have a mane!
I'm going to stand fourteen hands high
On the Psychozoic plain!"
